Lumbar sympathetic neurolysis (LSN) is a treatment option for complex regional pain syndrome (CRPS). We examined whether LSN-related temperature changes are associated with clinical outcome and investigated relationships between the outcome of LSN and clinical variables in patients with CRPS-I. ⋯ LSN may be effective in some patients with CRPS, irrespective of temperature changes and temperature asymmetry pattern. A short duration of pain and concurrent cold intolerance significantly predict successful LSN.

Stereotactic radiosurgery (SRS) represents an expanding approach for neurosurgeons and radiation oncologists. We evaluate educational gaps of senior residents drawn from each specialty as part of a focused SRS course. We also evaluate the strengths and limitations of SRS training in current residency programs of the course residents and faculty. ⋯ Knowledge and training gaps in SRS appear evident to the senior residents and faculty of both specialties. We believe that other educational opportunities for SRS experience are necessary to optimize clinical competency, as well as meet future clinical staffing needs for this expanding, multidisciplinary approach. Further evaluation of gaps in SRS is necessary through a larger, nationwide survey of U.S. neurosurgeons, program directors, and residents.

This study was performed to evaluate the efficiency of Gamma Knife surgery (GKS) on reducing recurrence of World Health Organization (WHO) grade II meningiomas after surgery and to define the risk factors associated with tumor recurrence/progression and patient's death. ⋯ There was no significant PFS or OS benefit for patients with WHO grade II meningiomas treated with adjuvant/salvage GKS postoperatively. Convexity meningiomas with gross total resection tended to benefit PFS. We suggest trying to achieve maximum safe gross total resection for patients with WHO grade II meningiomas, then following up closely.

The age of closure of skull base synchondroses has never been analyzed in a homogenous population of children with Crouzon syndrome. ⋯ In children with Crouzon syndrome, synchondrosis closure occurs prematurely, with a time course specific to each synchondrosis.

A 53-year-old man was admitted to our hospital following a traffic accident. He had been riding a bicycle and was knocked down by a motorcycle, injuring the right side of his forehead. Upon arrival at our department, he was conscious and we found no cerebrospinal fluid rhinorrhea or otorrhea. ⋯ Repeat computed tomography 9 hours later showed partial absorption of the pneumocephalus, which was almost completely absorbed 4 days later. He recovered well and was discharged after 7 days. At the 1-month follow-up, the patient was well, although the reduced vision in his right eye persisted.
